CONTROLLING STRATEGIES OF INDOOR CHEMICAL POLLUTION IN RENOVATED SCHOOL BUILDINGS

Abstract

The purpose of this study is to validate controlling strategies of chemical pollution in buildings after renovation. Several chemical substances were emitted from architectural materials, and there were complaints of unpleasant odors caused by VOCs in the renovated rooms by occupants. Two types of strategies were used in the renovated offices to solve this problem; forced ventilation with hot-humid outdoor air and a chemical filter in indoor air conditioning units were applied and their performances were validated by measuring the indoor concentration before and after operation. The results show that both strategies have a significant effect on reducing VOCs practically.
